I'm looking at a picture of a similar board but it isn't very clear to see, not focused.
Image of the board.. if something is causing diode to get shorted, do we need to look before diode or after?
That diode and one next to it (second adn third diode) are connected to the transformer pin. I guess that in the middle is the transformer? Another two diodes are connected to the oppsoite transformer pin
a diode that failed from reverse voltage in excess of the breakdown voltage of the diode will tend to fail to a short, while one that failed from excessive forward current leading to overheating will tend to fail open, but that is not guaranteed.
All 4 caps are on the shorted diode path, plus sign of caps are on that line.
What to test on it? Voltage or? I need to solder diode back before testing it with power on?
Yes, one of the connections from big transformator in the centre of the board was broken i guess. I removed solder from all these connections and added new solder at these spots, and it's working after that. There is a video on youtube, some guy fixed his samsung tv with reflowing these spots but cant find it now.
So you couldn't be bothered to come back and type a sentence that you fixed it by reflowing the solder joints, you are no more important than the rest of us, right?
